Understanding methane adsorption behavior on deep shales is crucial for estimating the original gas in place and enhancing recovery shale formations. In this study, within lower Silurian Longmaxi formation from Sichuan Basin, South China was conducted at pressures up to 50 MPa. The effects of total organic carbon (TOC), temperatures, clay minerals, moisture content capacity were discussed. results indicated that excess increased, then reached its peak, finally decreased with pressure. data...
Efficiently and accurately understanding the fluid flow behavior in ultra-deep natural gas reservoirs is very challenging due to complex geological environment intricate properties at high pressure. In this study, a fully coupled geomechanical model was developed simulate production phenomena reservoirs. Stress-dependent porosity permeability models were applied, then governing equations of incorporated into COMSOL Multiphysics. Furthermore, verified by reservoir depletion from Keshen field...
The quantitative characterization of adsorbed gas and free in shale reservoirs is a key issue exploration development gas. Thus, the aforementioned topic great significance to evaluation reserves, screening favorable target areas, formulation plans. However, research on our current understanding quantities deep still lacking. To address this problem, shales from Longmaxi Formation southern China were collected conduct high-pressure isothermal adsorption experiments. model was used describe...
The advancements in hydraulic fracturing and horizontal drilling techniques have substantially facilitated the large-scale extraction of natural gas from shale reservoirs. However, use fracking water poses several potential drawbacks including contamination groundwater, surface water, soil, as well risks to air quality. Due unique physical properties supercritical CO2, exploitation using this method has been considered a promising technology that can not only improve recovery but also enable...
Granular samples are often used to characterize the pore structure of shale. To systematically analyze influence particle size on characteristics, case studies were performed two groups organic-rich deep shale samples. Multiple methods, including small-angle neutron scattering (SANS), low-pressure nitrogen gas adsorption (LP-N2GA), carbon dioxide (LP-CO2GA), and XRD analysis, adopted investigate how crushing process would affect parameters fractal features The research indicates that with...
Abstract Gas flow behavior in porous media with micro- and nanoscale pores has always been attracted great attention. transport mechanism such is a complex problem, which includes continuous flow, slip transition flow. In this study, the microtubes of quartz microcapillary nanopores alumina membrane were used, gas measurements through diameters ranging from 6.42 μm to 12.5 nm conducted. The experimental results show that characteristics are rough agreement Hagen-Poiseuille (H-P) equation...
Despite the success of deep horizontal drilling and hydraulic fracturing in yielding large production increases from unconventional shale gas reservoirs, uncertainties associated with basic transport processes require understanding order to improve efficiency minimize environmental impacts.

In this study, adsorption diffusion measurements Longmaxi Formation were conducted at 30℃ 50℃for relative...
Abstract Large volumes of water are used for hydraulic fracturing low permeability shale reservoirs to stimulate gas production, with most the remaining unrecovered and distributed in a poorly understood manner within stimulated regions. Because partitioning into pores controls release, we measured saturation dependence on relative humidity ( rh ) capillary pressure P c imbibition (adsorption) as well drainage (desorption) samples Woodford Shale. Experiments modeling vapor adsorption laminae...
